“…A systematic experimental study should be carried out to obtain suitable fabrication parameters for SLM technology. In previous research [16] the present authors have designed an orthogonal experiment to optimize the parameters for 316LL stainless steel in SLM. During the SLM process, the supports can be regarded as thin-walled parts, since they are always very thin.…”

“…The part fabricated by SLM is built layer upon layer, and the interface between layers is fragile. However, the compact microstructure is often characterized mainly by quite fine grains, because of rapid solidification [16]. The part by fabricated SLM has improved mechanical properties, which implies that the fabricated nonassembly mechanisms can be useful for practical applications.…”

When fabricating metallic mechanism joints by selective laser melting (SLM), the clearance of the joint and the fabrication direction are two important factors, which are studied in this paper. In order to reduce joint clearance and facilitate the removal of support material, two improved joint designs are proposed: one with a drum-shaped hub design, and one with a drum-shaped pin design. As well as joint clearance, part strength is also very important. Sample tensile test parts were fabricated by SLM and tested for yield strength and elongation: these mechanical properties were comparable to those of equivalent parts produced by casting. For experimental verification, a number of metallic joints are fabricated. Since non-assembled metallic mechanisms produced by SLM have strength that can stand large loads, they have the potential to be used directly as mechanical power transmission systems in some practical applications.

“…Many national and international teams have done a lot of empirical researches in recent years and have made great progresses in materials, processing technology and applications. Yadroitsev's group has set up the experiment to succeeded in fabricating the thin walled parts that wall thickness is 140µm [11] , Wu's group had gotten the high density Cu-based alloys parts [12] , Child's group study the relation between power output and melting through the simulation and algorithm analysis [13] , Wang's group optimize the parameters of 316L stainless steel through orthogonal test and got high-density parts [14] . Some foreign companies have directly manufactured many complex parts, such as cooling parts, individuality dental crown and gear [16] .…”
